Overview of Police Interrogation Techniques Good Cop/ Bad Cop Routine This is an oft used technique in police departments when dealing with youthful or inexperienced offenders. Two interrogators present opposing stances to the suspect; one as a rogue punisher who uses threats and verbal attacks and the other as a defender willing to protect the suspect and sympathize with them. People respond and are more willing to open up and confide in someone they feel safe with, and so the 'good' cop is able to take advantage of this rapport and use further psychological manipulation to gather information.

Overview of Police Interrogation Techniques Deception An interrogator who has been trained in psychological manipulation attempts to build rapport with the suspect by feigning interest in something the suspect deems important eg. a hobby, political ideology, racial or gender bias, alternative lifestyles etc. The goal is to get the suspect to loosen up and be comfortable talking. Once the suspect believes the detective is like him in interests or beliefs, he is likely to let down his guard and open up, giving vital information that can be utilized further in the interrogation process if necessary.

In other words, by observing the interviewees facial and body movements during and after answering the question, the detective gets an idea of how they normally respond when they are telling the truth. This is vital information to be used in vetting any deceptions as the intensity of the interrogation increases.

Overview of Police Interrogation Techniques Neurolinguistic Interviewing This is an expansion of the Kinesic interviewing technique where the detective will attempt to establish how the interviewee's brain works when they are thinking or recalling events. This is achieved by asking the suspect various questions that will cause them to access different parts of the brain and is determined by observing their eye movement. When asked a non threatening question that requires them to use memory eg. " what year did you graduate from High school?", their eye movement will move to the right since they are accessing the memory center in the right hemisphere of the brain. A question requiring the suspect to think or analyze (or make up information) could elicit eye movement upward, down or to the left. After establishing this behavioral responses, the detective will then immediately ask questions directly related to the crime in question and make a note of the non-verbal responses accordingly.
